Robot Conceptualization

So I did some heavy conceptualization of the robot. I narrowed down the possibilities by limiting him to either wheels or treads (no legs) and tried to make him cute, without making him look like wall-e. There were two directions that I wanted to take him. Either streamlined (such as american machine age design), or steampunk (a sub genre of fantasy, set in an era or world where steam power is still widely used, here is a wikipedia link).

I am completely fascinated by mid-century American design, streamlined things in particular. Here is some reference I found for that type of design:








And here are some steampunk references:







And here are the results. I have posted a plethora of designs. After conferring with my cohorts, I created a new design and made some color concepts which would best reflect my most recent progress.
